Patient Guide
This guide explains lung cancer surgery in simple terms—who may benefit, how much lung may need to be removed, the tests required before surgery, and what recovery usually looks like. If you are considering robotic or minimally invasive lung surgery in Mumbai, it will help you prepare informed questions for your consultation.
Understand the surgery visually
For suitable patients, a minimally invasive approach may offer:
The safest approach is chosen according to tumour location, complexity, previous treatment and patient fitness.
Symptoms that deserve evaluation
These symptoms can have many causes, but persistent or unexplained symptoms should not be ignored.
Persistent cough
Blood in sputum
Chest discomfort
Unexplained weight loss
Consult a specialist
Seek urgent medical attention for significant coughing of blood, severe breathlessness or severe chest pain.
Lung cancer surgery removes the tumour together with a margin of healthy lung tissue. Nearby lymph nodes are usually removed or sampled because this gives important information about the true stage of the cancer and whether additional treatment may be helpful.
The aim is to remove all visible cancer while preserving as much healthy lung as is safely possible. The amount removed depends on the tumour’s size, location, relationship to major airways and blood vessels, lymph-node findings, and your predicted breathing reserve after surgery.
Wedge resection
Removes the nodule or tumour with a small rim of surrounding lung. It is used selectively, depending on tumour size, location, diagnosis and lung reserve.
Segmentectomy
Removes one anatomical segment of a lobe together with its airway and blood supply. It can preserve more lung than lobectomy in carefully selected patients.
Lobectomy
Removes one complete lung lobe. This is a standard operation for many operable lung cancers and is usually combined with systematic lymph-node assessment.
Bilobectomy or pneumonectomy
Removes two right-sided lobes or an entire lung. These larger operations are required only when a smaller resection cannot remove the tumour safely and completely.
Sleeve resection
Removes a tumour-involved portion of a major airway and reconnects the healthy ends. In selected cases, this can avoid removal of the entire lung.
| Approach | How it is performed | When it may be used |
|---|---|---|
| Open thoracotomy | A larger incision between the ribs | Very large, central or technically complex tumours, or when open access is safest |
| VATS | Small incisions, camera and thoracoscopic instruments | Many early-stage and selected more complex resections |
| Robotic | Small incisions with surgeon-controlled articulated instruments and 3D vision | Suitable tumours where minimally invasive access is appropriate |
Many patients breathe comfortably during ordinary daily activities after lobectomy or a smaller resection. The remaining lung tissue expands and the body gradually adapts. Recovery varies: patients with emphysema, smoking-related lung damage, heart disease, reduced fitness or a larger resection may notice more breathlessness. Pulmonary function tests help estimate this risk before surgery.
Interesting fact
The right lung has three lobes and the left lung has two lobes, leaving space for the heart. Removing one lobe does not mean removing half of your total breathing capacity.
Stop smoking
Stopping at any stage is helpful and reduces chest and wound complications.
Walk and practise breathing exercises
Improving fitness before surgery may make mobilisation and recovery easier.
Improve nutrition
Protein-rich meals and correction of weight loss support healing.
Review medicines
Blood thinners, diabetes medicines and supplements may need specific instructions.
Lung surgery is a major operation. Your team takes multiple steps to reduce complications, but risks cannot be eliminated completely. They depend on age, lung and heart health, tumour complexity and the amount of lung removed.
For patients travelling to Mumbai
Bring the biopsy report and slides/blocks if available, CT and PET-CT images—not only printed reports—pulmonary function results, medication list and details of previous cancer treatment. Image review is important for planning.
This page provides general education. Individual treatment decisions require review by your thoracic oncology team.
Before surgery
Surgery day
Identity checks, consent and final preparation
You are fully asleep and continuously monitored
The planned lung resection and lymph-node assessment are performed
Close monitoring until you are stable
Sit up and walk the same day or next day when safe
Recovery calendar
Milestones vary according to the procedure, surgical approach and individual recovery.
DAY 1
✓ Sit up
Pain control and breathing exercises begin
DAY 2
✓ Walk
Short supervised walks and physiotherapy
DAY 3+
✓ Drain review
Removal when air leak and drainage are safe
WEEK 2
✓ Light activity
Daily walking and gradual return to routine
WEEK 6
✓ Near normal
Many patients have regained good independence
Drain removal is not guaranteed on day 3; some patients need it for longer. Extensive or open surgery generally takes longer to recover from.
Myth vs fact
Myth
“Removing one lobe means I will always need oxygen.”
Fact
Most suitable patients do not need permanent home oxygen after lobectomy.
Myth
“All lung surgery requires a very large incision.”
Fact
Many resections can be performed through VATS or robotic small-incision techniques.
Myth
“Exposing cancer to air during surgery makes it spread.”
Fact
Air exposure does not cause cancer spread. Surgery follows established cancer-control principles.

Surgery is most often considered for non-small cell lung cancer that appears removable and has not spread widely. Some selected locally advanced tumours may also be treated with surgery as part of a combined plan.
A lobectomy removes one complete lobe containing the tumour, usually together with nearby lymph nodes.
Many patients return to independent daily life. The final breathing capacity depends on the health of the remaining lung, fitness and the amount of lung removed.
Both use a camera and small incisions. VATS uses long thoracoscopic instruments; robotic surgery uses surgeon-controlled articulated instruments and three-dimensional magnified vision.
Many resections take approximately 2–5 hours. Complex sleeve resections, chest-wall resections or pneumonectomy may take longer.
Many patients stay about 3–7 days after minimally invasive lung resection. Recovery may take longer after open or extensive surgery, or if the chest drain must remain in place.
Usually yes. A chest drain removes air and fluid while the operated lung re-expands. It is removed when the air leak and drainage are at safe levels.
Most patients do not need permanent oxygen after limited lung resection. Temporary oxygen may be prescribed when oxygen levels remain low during rest or walking.
Return depends on the operation, pain control and type of work. Many patients resume light work in several weeks. Drive only when you can perform an emergency stop comfortably and are no longer taking sedating pain medicines.
The decision depends on the final stage, lymph nodes, tumour type and molecular test results. Some patients need no additional treatment; others may benefit from chemotherapy, immunotherapy or targeted therapy.
Bring CT and PET-CT images, biopsy reports and pathology material if available, pulmonary-function results, medication list, previous treatment details and relevant heart or lung records.
Seek urgent care for sudden or rapidly worsening breathlessness, severe chest pain, fainting, blue lips, coughing up significant blood, or rapidly worsening symptoms.
Pain is expected after any chest operation, but smaller incisions may reduce early discomfort for suitable patients. Modern pain-control methods help patients breathe deeply and walk sooner.
Many patients can climb stairs slowly after discharge, provided they feel steady and the treating team has not advised otherwise. Pause if breathless and increase activity gradually.
Flying is usually postponed until the lung has fully re-expanded and there is no remaining air leak or pneumothorax. Obtain specific clearance from your surgeon before booking travel.
Life expectancy depends mainly on the cancer stage, tumour biology, other medical conditions and treatment response. The operation is recommended when its expected cancer-control benefit outweighs the loss of lung tissue.
For appropriately selected patients and when performed by an experienced thoracic team, robotic surgery is an established minimally invasive approach. The safest method still depends on tumour and patient factors.
Choose balanced meals with adequate protein, vegetables, fruit and fluids. Smaller frequent meals may be easier when appetite is reduced. Follow individual advice for diabetes, kidney disease or swallowing problems.
Recurrence is possible, which is why pathology review, additional treatment when indicated, and regular follow-up scans are important after surgery.
Sometimes. Wedge resection or segmentectomy may be appropriate depending on the nodule’s size, depth, location, diagnosis and the patient’s lung reserve.
